Busy area, but not at 6:30am. Odd that it blew 30 minutes after it was identified, almost as if it was remote and they wanted it to at least blow and not be found intact. On a nice day the block with the wild horse saloon, one block away has hundreds of pedestrians. Other clue, Christmas Day, a religious Holiday.
Warning call- re: suspicious vehicle. hmmm
Possible motive to kill first responders by luring them in... blm / antifa- at top of THIS list.
High energy explosive of unknown (large) # of lbs... ROP.
Bombing on Christmas Day / religious holiday... ROP.
